Michaels, play-by-play man on NBC's Sunday Night Football NFL coverage and the broadcaster who proclaimed "Do you believe in miracles?" at the 1980 Winter Olympics, was arrested for driving under the influence at about 9:30 p.m. Friday, according to Sgt. Richard Lewis, public information officer for the Santa Monica Police Department.

"He makes an illegal U-turn in a business district. ... Two motor officers see that. They're staged in a gas station lot. They see the illegal U-turn, and they go after him," Lewis told USA TODAY Sports on Sunday.

"They do a traffic stop. During that stop, they smell alcohol and determine he is under the influence. They do a field sobriety (test) and they arrest him.''

Lewis declined to specify Michaels' blood alcohol level. Michaels, 68, was charged under California law with DUI of alcohol and driving with a blood alcohol level of .08 or more.

Lewis said Michaels was booked and released about 6-8 hours later. The Santa Monica Jail confirmed Michaels was detained.

The Santa Monica Police Department was conducting a DUI/driver's license checkpoint Friday night. Lewis said Michaels did not go through the checkpoint.

"But those motor officers were working the checkpoint, and they just saw his illegal turn,'' Lewis said.

NBC Sports issued a statement: "We are aware of the situation, and we've spoken to Al. We have no further comment at this time."

Earlier this month, the Santa Monica police had announced they would conduct the DUI/driver's license checkpoint on Friday, at an undisclosed location.

"All too often, members of our community are senselessly injured or killed on local roadways by impaired drivers," Lt. Jay Trisler said in an April 12 news release announcing the checkpoint. "Over the course of the past year, traffic collisions involving impaired drivers/riders were involved in 91 collisions, which have killed three and injured 28 people."

Michaels worked about three decades with ABC Sports before moving to NBC in 2006. At ABC, he was play-by-play voice of Monday Night Football for 20 seasons and made his "believe-in-miracles" call at the 1980 Winter Olympics after the USA's hockey victory against the heavily favored Soviet Union.

Michaels, a native of Brooklyn, N.Y., was inducted this year into the Television Academy Hall of Fame. He has a star on the Hollywood Walk of Fame.
